The MMA6900Q and MMA6901Q are dual axis, low g, xy sensors based on Freescale’s HARMEMS technology with an embedded DSP ASIC allowing for additional processing of digital or analog signals. The MMA6900Q has a ±3.5g full-scale range per axis and the MMA6901Q has ±5g full-scale range per axis.

Features

Sensitivity in x and y axes
±3.5 or ±5.0g full-scale range per axis
AEC-Q100 qualified, revision G, grade 2 (-40 ≤ TA ≤ 105 °C)
50 Hz second order low-pass filters
Unsigned 11-bits digital data output
SPI-compatible serial interface
Capture/hold input for system-wide synchronization support
3.3 or 5.0-volt single supply operation
On-chip temperature sensor and voltage regulator
Bi-directional internal self-test
Minimal external component requirements
Pb-free 16-pin QFN package
Pulse-code modulated output available for device evaluation


Target Applications

With a �3.5g or �5.0g full-scale range, the high-accuracy sensor enables electronic stability control (ESC) designers to accommodate higher original signal noise level without sacrificing resolution.
